Presentation Transcript

  1. Section 4-4 & 4-6“Cellular Respiration / Fermentation” Write everything that is BLACK

  2. 4.4 KEY CONCEPTThe overall process of cellular respiration converts sugar into ATP using oxygen

  3. mitochondrion animal cell Cellular respiration makes ATP by breaking down sugars. • Cellular respiration is aerobic (requires oxygen) • It happens in the mitochondria

  4. Glycolysis must take place first. • anaerobic process (does not require oxygen) • takes place in cytoplasm • splits glucose into two three-carbon molecules • produces two ATP molecules

  5. 1 ATP mitochondrion matrix (area enclosed by inner membrane) and 6CO 2 energy 2 3 energy from glycolysis ATP inner membrane and and 6H O 6O 2 2 4 Cellular respiration is like a mirror image of photosynthesis. • The Krebs cycle transfers energy to an electron transport chain. • takes place inmitochondrial matrix • breaks down three-carbonmolecules from glycolysis Krebs Cycle • makes a small amount of ATP • releases carbon dioxide • transfers energy-carrying molecules

  6. 1 ATP mitochondrion matrix (area enclosed by inner membrane) and 6CO 2 energy 2 Electron Transport 3 energy from glycolysis ATP inner membrane and and 6H O 6O 2 2 4 • The electron transport chain produces a large amount of ATP. • takes place in inner membrane • energy transferred to electron transport chain • oxygen enters process • ATP produced • water released as a waste product

  7. The equation for cellular respiration: C6H12O6 + 6O2  6CO2 + 6H2O • The reactants in photosynthesis are the same as the products of cellular respiration.

  8. 4.6 KEY CONCEPTFermentation allows the production of a small amount of ATP without oxygen.

  9. Fermentation allows glycolysis to continue making ATP when oxygen is unavailable. • Fermentation is an anaerobic process • occurs when oxygen is not available for cellular respiration • does not produce ATP

  10. Lactic acid fermentation occurs in muscle cells • glycolysis splits glucose into two pyruvate molecules • pyruvate and NADH enter fermentation • energy from NADH converts pyruvate into lactic acid • NADH is changed back into NAD+

  11. Alcoholic fermentation is similar to lactic acid fermentation • Fermentation is used in food production. • yogurt • cheese • bread

  12. Pages 5, 6, & 7 • Page 5 Title this page Cellular Respiration -What is the function of cellular respiration? -What is the difference between aerobic and anaerobic? -Which of the above does cellular respiration require? -What does the kreb cycle do? -What does the electron transport chain do? 2. Page 6 Title this page COMPARING PROCESSES -On page 115 draw figure 4.12 and under each drawing write the equation that fits the drawing

  13. Page 7 Title this page Fermentation -Write the key concept for fermentation Which type of process is fermentation? What does that term mean? -Describe the difference between Lactic acid fermentation and alcoholic fermentation. -Give 3 examples of alcoholic fermentation
